SIDEHILL GANG-PLOW.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed August 16, 1916. I Serial No. 115,176.

To all whom it may concern."

Be it known that 1, Jules G. B. MANS- FIELD, a citizen of the UnitedStates, 'residing at Gorda in the county of Monterey and State ofalifornia, have invented new and useful Improvements in Sidehill Grang-Plows, of which the following is a specificationf This invention relatesto a side hill gang plow. 7

One of the objects of the present invention is to provide a gang plowparticularly adapted for-side hill work in which the mold boards andshares are reversible to permit turning of the plow at the end of afurrow and turning of the land toward the down hill side.

Another object of the invention is to provide a plow of the characterdescribed which is simple, substantial and cheap to manufacture, and soconstructed and arranged that the movable parts of the plow are firmlyand securely mounted.

Another object of the invention is to provide a structure which willpermit the plows to automatically reverse when the plow frame is turned.

Further objects will hereinafter appear.

The invention consists of the parts and the construction andcom'binationof parts as hereinafter more fully described and claimed,having reference to the accompanying drawing in which Figure 1 is a planview of the plow.

Fig. 2 is a side elevation of the same having one mold board broken awayor removed to show its support.

Fig. 3 is a plan viewof the plow, showing the position of the moldboards'and supporting frames while making a turn.

Fig. 4 is an end View ofFig. 3.

Fig. 5 is an end view of Fig. 1.

Fig. 6 is a detailed View of a latch employed in looking the mold boardagainst reversible movement. j i

Referring to the drawings in detail, A indicates in general a plow framewhich in this instance is made intwo sections 2 and 3. These sectionsare connected by means of a pair of cross-links 1 which are pivotallyattached as at 5 to the respective frames.

Journaled in each'frame section near the forward endis a crank'a'xlefi,and mounted on each crank axle is a supporting 'wheel 7. Pivotally'mounted asst 8 extension 9 tion.

formed at each end of the rear connecting cross link 4:, is a'block 10which supports a rack 11 and a lever 12. The lower end of each lever isconnected by a link 13 to the crank arm of the respective axles 6 andpawls 14 engageable with the racks 11 permit the levers to be moved andlocked in any position with relation thereto, thus providing a means forraising and lowering each supporting wheel with relation to its frameindependently of the other. Each frame has a goose-necked beam 15 on thelower end of which, as at 16, is a mold board 17 on the forward end ofwhich is formed a share 18. The mold boards and shares provided aredouble faced, and therefore permits the mold boards and shares to beswung about the pivots 16 to assume the position indicated in Fig. 5, ora reverse position when the plow is traveling in the opposite direc-Pivotally connecting each mold boardis a U shaped .cross bail or bar 19,and pivotally connecting the rear ends of the respective frames 2 and 3is a cross bail 20.

This bail is mounted directly above the bail 19, and means hereinafterto be described is provided for securing said bails together when theplow is traveling in either one direction or the other. Connecting theforward. ends of the respective frames 2 and 3 is a draw bar 21, andslidably mounted on said draw bar is a shackle 22 to which the team ishitched. Connecting the shackle 22 with a pivotally mounted arm 23 is apair of chains 24, and pivotally attached to the cross links 4: is arearwardly extending handle 25. Mounted on the lower end of the saidhandle beam in alinement with the cross bails19 and 20, is a latch 26.The forward 'end of this latch is provided with a projection 27 which isadapted to engage bar 19 and secure it against lateral movement withrelation to the bail 20, the latch being operated in any suitable mannerby the pivotgrip 28 and connecting In operation referring to Fig. 1,when the plow is working on the side hill and traveling in the directionof arrow the frames 2 and 3 will assume the position shown in Fig. 1.The shackle 22 will assume the dotted line position shownat 22 The lineof pull is thus central with relation to the supporting wheels and themold boards, an'dthe soilthroWn up when the furrow is cut is 1 alwaysturned toward the downhill side.

retracted by means of the grip 28 to release The team is then turnedaround in the direct on of arrow 6 to turn the plow as a wholeto assumethe correct position when traveling in the opposite direction. I

The turning of the plow as a whole by the pull of theteam causes theframe 2 to swing with relation to the frame 8 about the crosslinks at,and in this manner [causes it to assume a forward position with relation'to the frame '3. The pressure of the soil against the mold boards 'at'the same time causes these to swing downwardly about their pivots andupon, the opposite side to the reverse position and they are in thisman'- ner automatically turned to throw the soil toward thedownhill'side when traveling in the opposite direction. The releasing ofthe l'atch'26 permits the U shaped beam 19 to swing-"with relation tothe cross-beam 20 when the mold boards are turned, but the bails areagain locked with relation to each other by the latch the moment themold boards have been completely reversed. The team may then againbestarted and the next furrow cut.

The adjustable mounting of the supporting wheels 7 permits these to beraised and lowered and to act alternately either as a furrow wheel or asa land-side wheel; It can furthermore be seen that the pivoted mountingof the racks'll, together with the levers 12 mounted thereon, permitsone crank axle 7 to swing ahead when one frame swings ahead of theother. The angular position of the cranks is therefore changed while thevertical adjustment remains constant, unless changed by changingtheposition of the levers 12. The lever 23 provided with connected chains24;, .is merely used for pulling the shackle from one end of the drawbar to the other, inturning, it otherwise remains stationary andmaintains one chain taut while the other is slack. The pivotalconnection of the cross-links 1 always permits one frame to advance withrelation to the other when making a turn, this being of great importanceas it permits the mold boards to automatically turn or reverse when theframes are turned. i

The whole construction shown is simple, substantial, and cheap tomanufacture, and so arranged that the movable parts of the plow arefirmly and securely mounted, and practically any depth furrow may besecured.

The materials and finish of the several parts of the plow may be such asthe experience and judgment of the manufacturer may dictate.

I wish it understood that various changes in form, proportion and minordetails of construction may be resorted to within the scope of theappended claims, and that I do not wish to limit myself to the specificdesign of construction here shown.

Having thus described my invention, what I claim and desire to secure byLetters Patent is L 1. In a side hill gang plow, a pair of movablyconnected frames, a reversible combined mold board and plow share oneach operable by contact with the soil on turniiig'the frames, and adraft-operated means for relatively moving the frames to position oneshare with its mold board in advance of the other.
